Hydraulic Press safety questions

At home I have a 50,000 kg hydraulic press.....haven't had any issues with it....when pressing off old axle bearings, wrap a heavy rag around it, like old jeans...if the bearing shatters, the rag catches it.
At work, I use a 200,000 kg electro-hydraulic press.....some of the stuff I press together or apart can be as much as 80,000 kg pressure.
This is footage I took at work.....that pin being pressed in weighs about 88 lbs.

When assembled, that 2nd Reduction unit weighs about 1,800 kg.
